May Snow Barrage Hits Montana, Wyoming Peaks
21 May
Summary
- Over a foot of snow expected in mountainous areas.
- Winter storm warnings issued for southern Montana.
- Travel disruptions and safety risks are a concern.
A significant late-season winter storm is set to impact mountainous areas of Montana and Wyoming, with heavy snowfall expected to continue through Thursday, May 22, 2026. Some higher elevations could see over a foot of accumulation, prompting a winter storm warning for southern Montana's Absaroka and Beartooth Mountains. This May snowfall, while not entirely unusual at high elevations, carries the potential to disrupt travel and outdoor activities.
The National Weather Service has issued advisories for both states, with projections of 8 to 13 inches of snow in warned areas and 5 to 10 inches in advisory zones. Gusty winds accompanying the snow will further reduce visibility, creating hazardous conditions. Travelers are strongly advised to carry emergency supplies and exercise caution, especially on routes like U.S. Route 14.
Lower elevations are expected to experience rain and thunderstorms as a cold front moves through the region. Meanwhile, the Great Lakes region is facing cold weather, with frost advisories and freeze warnings in effect for parts of Minnesota, Wisconsin, and Michigan.
